Hi guys I wanted to ask you if it has any ? happened, today I read a bmw 320d year 2005 Bdm is mounted with the ecu edc15c35.. by changing the map with ecm, saving it, and rewriting it in the bdm, the car part.. reloading the original file of the car is great.. at the beginning thinking it was the problem in the phase of scrittuta I have rewritten the file but nothing... what am I ? seemed a bit strange... as the ecm, I found only a single driver.. while if I search manually I find more? one.. with the same hw and sw... according to me it is some problem of checksum calculated.. bad.. I have uploaded the file winols for the calculation of the checksum I saved.. and I noticed that the checksum has been calculated differently..tomorrow I try to write the processed file with winols to verify
